| 摘 要： | 用CIRAS-1型便携式光合系统对盆栽寒富苹果的光合特性进行了研究。结果表明,在冷凉地区,寒富苹果光合速率日变化呈双峰曲线,中午前后光合速率下降,出现“午休”现象,光照强度、气温等因子对光合作用产生影响。寒富苹果的饱和光强为(1 291±58)μmol/(m2.s),光补偿点为(32±8)μmol/(m2.s);CO2饱和点和补偿点分别为(1 439±21)μmol/mol和(92±6)μmol/mol。 |

| Abstract: | The photosynthetic characteristics of Hanfu apple in pot were studied using CIRAS-1 portable photosynthetic system.The results showed that the diurnal variation of net photosynthetic rate presented double-peak curve in cool regions,with the first peak occurred at 10:00 a.m.and the second peak after 15:00 p.m,while decreased at noon.The net photosynthetic rate was greatly affected by light intensity and air temperature.The light compensate and saturated points of Hanfu apple were(32±8)μmol/(m2·s)and(1291±58)μmol/(m2·s),respectively.The CO2 compensate and saturated points were(92±6)μmol/mol and(1439±21) μmol/mol,respectively. |
